3 Claims. (Cl. 139-403) This invention relates to a woven fabric and method of weaving the same.

It is an object of the invention to weave a loop pile fabric on a loom such as disclosed in our prior application filed March 20, 1956, Serial No. 572,657, wherein pile yarns of different twists in alternate relation are carried over one, two, three or more of the gauge wires in one direction and then carried over the gauge wires in the opposite direction to provide rows of loops in angular relation to the loops in other rows, with the loops formed from yarns of one twist having a different appearance from loops formed from yarns of the other twist whereby a new and novel texture effect is produced.

:In the, accompanying drawings forming a part of this specification and wherein like numerals are employed to designate like parts throughout the same.

Fig. 1 is a plan view of a fabric woven in accordance with our invention,

Fig. 2 is a cross section of the fabric in Fig. 1, showing a fragment of one row of loops,

Fig. 3 is a perspective view showing theweave of a single pile warp yarn. r

Fig. 4 is a plan view of a'fabric of different design made in accordance with our invention, r

Fig. 5 is a cross section of the fabric in Fig. 4 showing a fragment of one row of loops,

-Fig. 6 is a cross section of the fabric in Fig. 4 showing a fragment of a different row of loops.

Fig. 7 is a view of the S and Z twist pile yarns used in weaving the fabric.

In the drawings, fabrics are shown made in accordance with the method which may be carried out on the gauge type loom disclosed in our prior application Serial No. 572,657. In carrying out the method, pile yarns are carried by-a series of needles over gauge wires and down into the ground warps to be tied intothe ground by the usual weft shots. The needles are then swung upwardly v and moved weftwise to carry the pile yarns over and down on the opposite side of the gauge wires. The mechanism for operating the slide bar supporting the needles is modified to move the needles over one, two or more gauge wires in one direction and then in the reverse direction, or to move the needles successively over a number of gauge wires in one direction and then in a reverse direction.

The pile yarns employed in the method are S and Z multi-ply twist yarns 5 and 6 which when carried over the gauge wires form pile loops 7 of a fabric 8. Each weftwise row of loops includes 8 and Z twist yarns arranged in alternate relation, with the loops in the rows being angularly disposed in relation to the loops in other rows. The fabric shown in Fig. 1 has each row of loops formed of S and Z twist yarns arranged in alternate relation with the yarns forming the loops in one row carried over two gauge wires before being tied between the chain warp threads 9 by the weft threads 10 and then carried in a reverse direction over the same two gauge wires to form the next row of loops. This causes the loops in each row to be angularly disposed with respect to the loops in adjacent rows and due to the different twist of the yarns forming the loops and change in the angular direction of the loops it will be seen the loops formed of one twist yarn will have a difiierent texture appearance to that of the loops formed of the other Z twist yarns arranged in alternate relation to sets of three 8 twist yarns, each yarn being carried by a separate needle. The yarns are carried over three gauge wires successively in one direction forming three rows of loops disposed in the same angular direction and then are carried back in the opposite direction over the same three gauge wires successively to form three rows of loops disposed in an angular direction opposite to that of the first three rows of loops. Due to the change in the angular direction of the loops and the different twists in the yarns it will be seen a pronounced design is formed in the texture of the pile.

The fabrics shown are preferred examples of the same and fabrics of different texture may be formed by varying the arrangement of the S and Z twist yarns or changing the action of carrying the pile yarns over one, two, three or more of the gauge wires in one direction and then reversing the action, or carrying the yarns over two, three or more of the gauge wires successively in one direction and then reversing the action. It is also possible to produce a texture effect by using only a S or Z twist yarn and carrying the yarn over a series of gauge wires in one direction and then over the same wires in a reverse direction, or the yarns can be carried over a series of wires successively in onedirection and then over the same wires in a reverse direction.

Having thus described our invention, we claim--- I. A loop pile fabric comprising spaced sets of ground warps interwoven with weft shots, pile warp yarns in the spaces between the sets of ground warps, said pile warp yarns being formed of twist ply-yarn with alternate yarns twisted in a reverse direction, each pile warp yarn passing under a weft shot and extending weftwise over a plurality of sets of ground warps in one direction, under a weft shot and then back over the same sets of ground warps in the opposite direction forming weftwise rows of pile loops disposed in different angular relation to each other.

2. A loop pile fabric comprising spaced sets of ground warps interwoven with weft shots, pile warp yarns in the spaces between the sets of ground warps, said pile warp yarns being formed of twist ply-yam with alternate yarns twisted in a reverse direction, each pile warp yarn extending over a plurality of sets of ground warps and under weft shots successively in one direction and then back over the same sets of ground warps and under the weft shots successively in the opposite direction forming weftwise rows of pile loops disposed in different angular relation to each other. 3. A loop pile fabric comprising spaced sets of ground warps interwoven with weft shots, pile warp yarns in the spaces between the sets of ground warps formed of multiply yarn with some of the yarns twisted in a reverse direction, each pile yarn passing over a series of sets of ground warps and under weft shots in a weftwise direction, and back over the same series of sets of ground warps and under weft shots forming weftwise rows of loops with the loops in one row in different angular relation to the loops in the other row.
